ZHUHAI, China (AP) A year after finishing the season as the No. 1-ranked player in the world, Angelique Kerber will be playing at the WTA Elite Trophy with an eye on 2018.

Kerber won the Australian Open and U.S. Open last year, but has struggled in 2017 and has dropped to No. 19.

''I'm not trying to look back at the year. I'm trying to look ahead and trying to end the year as well as I can by putting everything on the court, winning as many as matches as I can and going to my holidays with a good feeling,'' Kerber said. ''It's a tough tournament but it's an opportunity to get better, have good competition and maybe also going with a good feeling to next season.''

The WTA Elite Trophy is a round-robin tournament for the top players who failed to qualify for the WTA Finals. The tournament splits 12 players in four groups of three, with the group winners reaching the semifinals.

Kerber is in a group with Anastasia Pavlyuchenkova and Ashleigh Barty.
